filter_ref
computes the reference distance filter.
filter_ref(dist, groups_ind, ref, ...)
dist | The distance matrix. |
---|---|
groups_ind | A vector of group names each of the samples belongs to. |
ref | A string object specifying the name of the reference group. |
... | Additional arguments. |
A matrix object of filter values.
Reference distance filter function is defined as \(f(x_i;y,g) = 1-\textrm{median}_{y_j=g} d(x_i,x_j)\), where
tp_data <- chicken_generator(1) tp_dist <- dist(tp_data[,-1]) filter_ref(dist=tp_dist, groups_ind=tp_data$Group, ref = "Shank")
